CURLOPT_INFILESIZE_LARGE(3) Library Functions Manual
NAME
CURLOPT_INFILESIZE_LARGE - size of the input file to send off
SYNOPSIS
#include <curl/curl.h>
CURLcode curl_easy_setopt(CURL *handle, CURLOPT_INFILESIZE_LARGE,
curl_off_t filesize);
DESCRIPTION
When uploading a file to a remote site, filesize should be used to tell
libcurl what the expected size of the input file is. This value must be
passed as a curl_off_t.
For uploading using SCP, this option or CURLOPT_INFILESIZE(3) is
mandatory.
To unset this value again, set it to -1.
When sending emails using SMTP, this command can be used to specify the
optional SIZE parameter for the MAIL FROM command.
This option does not limit how much data libcurl actually sends, as
that is controlled entirely by what the read callback returns, but
telling one value and sending a different amount may lead to errors.
DEFAULT
Unset
